RAY HALLER, OF JASPER, INDIANA.

BREAD WRAPPING AND SEALING MACHINE.

Application filed April 21, 1923. Serial No. 633,689.

To all whom may cancer a:

Be it known that I, RAY HALLER, a c1t1- zen of the United States, residing at Jasper,

in the county of Dubois and State of Indiana, have invented certain new and useful Improvements in Bread Wrapping and Sealing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as wlll enable others skilled in the art to whlch 1t appertains to make and use the same.

The present invention has relation to a machine for folding the ends of a wrapper after the same has been placed about a loaf of bread and sealing the folds to prevent loosening of the wrapper or the entrance therein of dust or other foreign matter and to prevent loss of moisture and the drylng of the loaf.

Other objects and advantages will be apparent and suggests themselves as the nature of the invention is understood.

While the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from the nature of the invention.

Referring to the accompanying drawings forming a part of the application:

Figure 1 is a side elevation of a bread wrapping and sealing machine embodying the invention, showing the loaf with the wrapper placed thereabout mounted upon the plate preliminary to folding the ends of the wrapper,

Figure 2 is a side view with the plate depressed and the first or rear flap folded,

Figure 3 is a similar view with the second or front flap folded,

Figure 4; shows the third flap or the bottom flap folded,

Figure 5 shows the final step with the top gap folded and preliminary to sealing the Figure 6 is a top plan view,

Figure 7 an end view,

Figure 8 a detail view in perspective showing more clearly the pivoted folder for forming the first lap and the parts associated therewith,

Figure 9 is a detail sectional view taken on a vertical plane indicated by the line 9-9 of Figure 8, and

and attached thereto in Figure 10 is a sectional view of a modified form of supporting means for the depressible. article receiving seat.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The frame of the machine comprises a bed 1, arch supports 2 mounted upon the bed 1 any preferred way and a base comprising boards 3 and 4, the board 3 being 'rlgidly attached to the supports 2 and the board 4 having adjustable connection with said sup orts for lateral movement, whereby to adlipt the machine for different sized loaves.

The folding mechanism is located at one end of the frame and the sealing mechanism at the opposite end thereof. Ways or table members 5 are mounted upon the base and support the loaves of bread or other article to'be wrapped. Brackets 6 and 7 are secured to the rear ends of the ways 5 and depend therefrom, each having a vertical slot 8 for the reception of a rod 9 which is normally held elevated by means of a spring 10.. The bracket 7 has an inner extension 11 at its lower end and a corresponding extension 12 at its upper end and these extensions are provided at their inner ends with openings in vertical alinement to receive a stem 13 which is provided at its upper end with a plate 14 constituting a seat to receive the loaf of bread or other article to be Wrapped. The rod 9 passes through the stem 13 and moves vertically therewith and is directed in its vertical movement by means of the slots 8. Stud bolts 15 or analogous elements are applied to the upper ends of the brackets 6 and 7 and are disposed outwardly and pivotally and slidably support folders 16 which, in the operation of the machine, form the first or rear flap in the folding of the ends of the wrapper about the loaf of bread or other article. The folder 16 consists of flat arms of elbow shape, the lower member of each of the arms being provided with a longitudinal slot 17 to receive a stud bolt 15 upon which the folder is pivotally and slidably mounted. The rod 9 passes through the lower ends of the folders 16. Upon depressing therod 9, the folders 16 receive a combined pivotal and sliding movement which results in the formation of the first or rear fold at the ends of the wrapper I which has previously been placed about the loaf of bread or other article to be wrapped. Other brackets 18 are attached to the wa s A and support folders 19 which form t e lar size of 10a second or front flap in the folding of the wrapper. Each of the folders 19 consists of a strip having an end ortion 20 curved laterally, said strips beln their straight ends in para el relation and their curved ends 20 facing outwardly, whereby to engage the forward ends ofthe wrap r and fold the same rearwardly, where y to form the front flap. The folders 19 are disposed forwardly of the folders 16.

Other folders 21 and 22 are arranged forwardly of the folders 19 and are attached to the ways 5, the folders 21 being disposed below and inwardly of the folders 22. Each of the folders 21 and 22 consists of an elongated plate, the upper rear edge of each of the plates 21 being curved outwardly and the lower edges of the plate 22 being simi larly curved outwardly and downwardly. The folders 21 form the third or bottom flap and the folders 22 form the fourth or top flap.

The sealing mechanism comprises heaters 23 and coolers 24, each partaking of the nature of a plate. The plates 23 are adapted to be electrically heated and in the operation of sealing the wrapper melt the wax applied thereto, whereby the scaling is effected, the plates 24 serving to confine the folds until the wax cools sufficiently to prevent. loosening of the folds. The sealing mechanism is likewise attached to the ways 5 so as to be relatively adjustable therewith when adaptin the machine to the particuor article to be wrapped.

In practice the loaf of bread 25 or other article partly enveloped by the wrapper 26 is placed upon the seat 14 and pressed down ward, thereb depressing the seat 14 and operating the olders 16 which form the first or rear flaps 27. The article is now moved forwardly upon the ways 5 and between the folders 19, which form the second or front flaps 28. A continued forward movement of the article results in the formation of the third or bottom flap 29 and immediately thereafter the fourth or top flap 30. The article is now moved forwardly between the heaters 23 which melt the wax applied to the wrapper and seal the same in a manner well understood. As the loaf passes between the plates 24, the folded flaps cool and the wax securing the same sets, thereby completing'the sealing. The succeedin loaves effect a delivery of the loaves from etween the cooling plates 24. It will thus be understood that the operation may be readily and expeditiously performed since the loaf partly enveloped by the wrapper is placed disposed with upon the seat 14 and moved downwardly and forwardly, the ends of the wrapper being automatically folded and sealed without requiring any es ecial care on the part of the attendant ot er than applying the wrapper tothe loaf and placing the latter upon the seat 14 and pressing it downwardly and yieldably sup orts the seat 14. These parts operate in su stantially the same manner as herein described.

What is claimed is:

1. A wrapping machine having a table, a plate normally projected above the table, a bracket below the table provided with a vertically elongated slot, a stem carrying said plate, a rod movable with said stem and disposed in said slot, and folder members, said folder members bein engageable with the article supported on e p ate andbeing operable by said rod.

2. A wrapping machine having a table, a plate normally projected above the table, a bracket below the table provided with a vertically elongated slot, a stem carryin said plate, a rod movable with said stem an disposed in said slot, and folder members, said folder members being engageable with the article supported on the late and being operable by said rod, said bracket having lateral extensions, and said stem being slidably mounted through slots in said extensions.

3. A wrapping machine having a table, a plate normally projected above the table, a bracket below the table provided with a vertically elongated slot, a stem carrying said plate, a rod movable with said stem and disposed in said slot, folder members, said folder members being engageable with the article supported on the plate and being operable by said rod, said bracket having lateral extensions, and said stem being slidably mounted through slots in said extensions, one of said folder members having an elongated slot, and means extending from the bracket into the last mentioned slot to guide the movement of the folder members.

In testimony whereof I aflix my signature in presence of two witnesses.
